Remote visual inspection using borescope equipment is a non-destructive testing method that allows evaluation of engine internal parts like compressor blades for cracks or leaks without disassembling the engine. Borescope inspections can retrieve foreign objects and perform compressor blade repairs to keep engines in operation longer in accordance with aircraft maintenance manuals and engine manufacturer service bulletins. As a borescope inspector, it is important to be accurate and make safety-focused judgments, as improper assessments can result in personal and economic damages in the safety-critical field of aviation.
